Dirtyhip Posted January 5 Share #3 Posted January 5 Chemical oxidation. There are no black pits right? Black spots are somewhat normal. Could be caused by internal bruises Chop faster. 2 Link to comment Share on other sites More sharing options...

Old No. 7 Posted January 5 Share #5 Posted January 5 It's only oxidation. I'm doing the same thing, my dermatologist calls them wisdom spots. I think she's just jiving me. 2 1 1 Link to comment Share on other sites More sharing options...
Solution MickinMD Posted January 5 Solution Share #6 Posted January 5 Sweet potatoes contain a compound called chlorogenic acid and also contain iron compounds. When diced, the surface gets exposed to oxygen in the air and it reacts with the acid and iron to form the dark spots. 3 Link to comment Share on other sites More sharing options...
